If a fair coin is tossed 4 times, what is the probability, to the nearest thousandth, of getting exactly 4 heads?
Answer: The probability of getting exactly 4 heads in 4 tosses of a fair coin is 0.0625, or 6.25%.
Step-by-step explanation:
We can use the formula for combinations, which is:
n! / (r! * (n - r)!)
In this case, n is the total number of tosses (4) and r is the number of successes we want to count (4 heads). Plugging these values into the formula, we get:
4! / (4! * (4 - 4)!) = 4! / (4! * 0!) = 4! / (4! * 1) = 1 / 1 = 1
The probability of getting exactly 4 heads in 4 tosses of a fair coin is therefore 1, or 100%. However, this is assuming that the coin is not fair and always lands on heads. If the coin is fair, the probability of getting 4 heads in 4 tosses is actually much lower.
To find the probability of getting 4 heads in 4 tosses of a fair coin, we need to use the formula for binomial probability, which is:
(n! / (r! * (n - r)!) * p^r * (1 - p)^(n - r)
In this case, p is the probability of getting a head in a single toss of the coin (0.5), r is the number of successes we want to count (4 heads), and n is the total number of tosses (4). Plugging these values into the formula, we get:
(4! / (4! * (4 - 4)!) * 0.5^4 * (1 - 0.5)^(4 - 4) = 1 * 0.5^4 * (1 - 0.5)^0 = 0.5^4 * 1 = 0.0625
Thus, the probability of getting exactly 4 heads in 4 tosses of a fair coin is 0.0625, or 6.25%, to the nearest thousandth.
the accuracy of a sample is a measure of how closely it reports the true values of the population it represents. true false
A sample's accuracy is determined by how well it captures the genuine characteristics of the population it represents true
Accuracy is a measure of how closely a sample reflects the true values of the population it is representing. A sample that is accurate is one that accurately reflects the characteristics of the population it is representing. For example, if a sample is taken from a population of 1000 people, the sample should represent the diversity of the population, such as age, gender, race, and other characteristics. If the sample accurately reflects these characteristics, then it can be said to be accurate. The accuracy of a sample can be determined by comparing it to the population it is representing, either through surveys, interviews, or other data collection methods. If the sample closely matches the true values of the population, then it can be said to be accurate. If there are discrepancies between the sample and the population, then the sample is not accurate.

Samina gets 1/4 of the money that is left over.
Tom gets the rest of the money.
Tom says,
"I would have got more money if we had shared the £600 equally between us."
Is Tom correct?
You must show how you get your answer.
No. Tom is not correct.
If the money were split equally everyone would've gotten £200.
But, if everyone went by the mentioned distribution, then,
Rachel would get = 2/5 x 600 = £280
Remainder money = 600 - 280 = £320
Samina would get = 1/4 x 320 = £80
Tom would get the remaining money = 600 - (280 + 80)
= 600 - 360
= £240
Since, £240 > £200, Tom would be incorrect in saying he would have had more money if he had split the money equally.

Let the time taken by the airplane to meet the same altitude be t minutes
An airplane is preparing to land at an airport. It is 55800 feet above the ground and is descending at the rate of 3,500 feet per minute.

Step-by-step explanation:
Before we start solving, let's define what the coefficients of this quadratic equation is.
[tex]y = ax^2 + bx + c[/tex]
[tex]y = -x^2 + 8x + 12[/tex]
a = -1
b = 8
c = 12
⭐What is the axis of symmetry?
the vertical line that cuts through the vertex and makes the parabola into 2 symmetrical halvesequation: x=To find the axis of symmetry, we need to find the x-coordinate of the vertex.
Equation for the x-coordinate of the vertex:
[tex]x = \frac{-b}{2a}[/tex]
Substitute the values of a, b, and c into this equation and compute.
[tex]x = \frac{-(8)}{2(-1)}[/tex]
[tex]x = \frac{-8}{-2}[/tex]
[tex]x = 4[/tex]
∴ The axis of symmetry is x = 4
⭐What is the vertex of a parabola?
the absolute highest or lowest point of the parabolaTo find the x-coordinate of the vertex, you can use the formula: [tex]x = \frac{-b}{2a}[/tex].
To find the y-coordinate of the vertex, substitute the x-coordinate of the vertex and compute.
x-coordinate: 4
y-coordinate:
[tex]y = -x^2 + 8x + 12[/tex]
[tex]y = -(4)^2 + 8(4) + 12[/tex]
[tex]y = -(16) + 32 + 12[/tex]
[tex]y = -16 + 44[/tex]
[tex]y = 28[/tex]
y-coordinate: 28
∴ The coordinates of the vertex is (4,28)
